Run a continuous collapse-and-simplify pass that surgically removes indirection failing to earn its boundary. Use when the user says 'collapse pass', 'simplify pass', 'reduce indirection', 'shrink the surface', 'find what to delete', when asking to audit a package for dead abstractions, when reviewing a pull request, branch, or recent merged change for simplification (isolated in a worktree), or when the goal is a sequence of small refactor commits that delete more than they add. Pairs with code-audit (smell catalog), refactoring (per-change mechanics), one-sentence-test (cohesion gate), cohesive-clean-breaks (deep redesigns), approachability-audit (first-read sanity), and post-implementation-review (second-read after each commit).
How a workspace-backed app under `apps/*` is composed: the isomorphic doc factory (`create<App>`), the environment factories (`open<App>Browser` / `open<App>Extension` / tauri), the `#platform/*` build-time platform DI for multi-platform (Tauri) apps, the `session` singleton, daemon/script placement under per-project `workspaces/<app>/`, and the file layout itself. Use when creating a new app, naming or placing the iso/browser/extension factory, wiring `#platform/*` subpath imports for a Tauri seam, choosing between auth-gated (Shape A) vs module-singleton (Shape B), placing the session singleton, or registering daemon/script bindings.
Query/RPC layer with TanStack Query, defineKeys, service composition, runtime DI. Use for createQuery, createMutation, queries/mutations, reactive data management.
Create a slash-command `/goal` for long-running Codex or Claude Code work when the user explicitly asks for a `/goal`, agent goal, or completion condition. Outputs one goal line with the objective, starting context, validation evidence, and stop condition.
List 3-5 comparable apps when planning a UX surface to test category fit and surface high-leverage refusals. Use for "what do other apps do", identity, sync state, local-first design.
Draft a self-contained, copy-pasteable prompt so a fresh agent can continue without this thread. Use when the user says "hand this off", "compact this", "wrap up for the next session", "write a continuation prompt", "draft a prompt", "make a prompt I can copy-paste", "create a delegation brief", or invokes /handoff.

When TanStack AI behavior, createChat, streamed message parts, tool calling, approvals, provider adapters, or Svelte bindings affect correctness, ask DeepWiki a narrow question against TanStack/ai before relying on memory. Use it to orient, then verify decisive details against local installed types, source, or official docs before changing code.
Skip DeepWiki for repo-local chat persistence and UI patterns already visible in the app.
Use this pattern when you need to:
createChat.UIMessage values.MessagePart, tool-call, or tool-result parts.@tanstack/ai: chat, generation helpers, stream conversion, model-message conversion, and server tool definitions.@tanstack/ai-client: chat client state, stream processing, tool approval plumbing, and client tool results.@tanstack/ai-svelte: createChat, fetchServerSentEvents, and Svelte-friendly reactive state.@tanstack/ai-openai or @tanstack/ai-anthropic.toServerSentEventsResponse on the server and fetchServerSentEvents on the client for chat streams.MessagePart variants as a discriminated stream protocol. Render every known part deliberately and keep an unknown fallback for forward compatibility.StreamProcessor when replaying, debugging, or transforming stream chunks outside the normal chat client.chat.stop() or dispose the owner on unmount when a stream may still be active.aiEventClient observability events when diagnosing stream, adapter, or tool behavior.apps/tab-manager/src/lib/chat/chat-state.svelte.ts shows Svelte chat state, streaming, and tool approval handling, with the conversation list derived from the handle registry.apps/tab-manager/src/lib/chat/persistence.ts owns the device-local IndexedDB chat store behind ChatClientPersistence.apps/opensidian/src/lib/chat/ui-message.ts shows the persisted-message to TanStack-message boundary for workspace-backed chat history.packages/workspace/src/ai/tool-bridge.ts converts workspace actions into client tools and serializable server tool definitions.
